  "textContent": "An engine system includes an engine housing having an intake port to convey an incoming flow of intake air to a first intake valve opening and a second intake valve opening located downstream of the first intake valve opening. A port fuel injector assembly is supported in the engine housing and includes a fuel injector within a sleeve and an outwardly opening fuel injection valve. The sleeve includes a fuel-directing cap extending into the intake port and forming a fuel injection opening defining an outgoing fuel path axis oriented at a fuel exit angle, to improve distribution of a gaseous fuel such as a gaseous hydrogen fuel to the respective intake valve openings for mixing and combustion in an engine cylinder. Related apparatus of a port fuel injector assembly and methodology is also disclosed. head portion",
